Rancher WebGUI is not accessible

Rancher WebGUI gives “default backend error - 404”

I installed the RKE cluster and on top of that Rancher server with the help of helm charts.

i followed the instructions mentioned in the below documentation:
Rancher Docs: Install/Upgrade Rancher on a Kubernetes Cluster
and allowed the http and https traffic on port 443 in the security group as well.

However, on access the GUI via the i am getting below error:

default backend error - 404

Can someone suggest what could be the issue here?


Hi @Ankit_Sharma1 , I hope you’re doing well.
I’m having the same problem here and idk how to go about.
did you make any headway? did you find a way to fix it?

hi ! do you get deployment “rancher” successfully rolled out when you check the rollout status? something like this:

kubectl -n cattle-system rollout status deploy/rancher
Waiting for deployment "rancher" rollout to finish: 0 of 3 updated replicas are available...
deployment "rancher" successfully rolled out
